Credit: A bird's-eye view of quantum error correction and fault tolerance by Arthur Pesah In a sign that the wave of error correction research we saw in 2024 will not only continue but accelerate in 2025, three new error correction papers, two from Google AI and one from a Harvard/MIT/QuEra team, have been posted on arXiv showing continued advancements from some of their previous research. The first paper from Google is titled Scaling and logic in the color code on a superconducting quantum processor which shows the results of their implementation of a different error code on their recently announced Willow [...]

Since the first Quantum Computing Report (QCR) articles were published in August of 2015, we have posted over 2400 articles that cover all aspects of quantum technology, the quantum market, and the quantum ecosystem. So, what happens to all those old articles after they are initially read? Are they thrown away and forgotten? No way! Global Quantum Intelligence has implemented a unique system for capturing, cleaning, and storing the quantum data we collect that we call the GQI Factory. We maintain a massive database of information relating to quantum including all the QCR articles as well as all of our reports, GQI proprietary [...]

The Unitary Fund has released the results of its annual Quantum Open Source Survey (QOSS). It contains responses collected from over 1100 respondents around the world during the survey's open period from September 16 to October 31, 2024. (See our previous article encouraging people to response to the survey here.) The survey requested responses in the areas shown below. Demographics Experience Cloud services Full-stack development platforms, compilers, and simulators Software for applications and tools User experience Open Source Software (OSS) Development & Research Community Questions probed such topices as who is using quantum computing, why they are using quantum computing, what [...]

2024 has seen an unprecedented wave of quantum computing roadmaps, with thirteen players either announcing new development paths or significantly updating existing ones. Never before has the industry seen such a concentrated period of concrete technical commitments and public timelines, marking a shift from general promises to specific, measurable goals. Recent Roadmap Announcements The following list summarizes this year’s developments: New Roadmaps QuEra Computing (January 2024): Three-year roadmap through 2026, targeting 100 logical qubits. Infleqtion (February 2024): Four-year roadmap through 2028, planning for over 100 logical qubits with 40,000 physical qubits. Pasqal (March 2024): Five-year roadmap through 2028+, targeting fault-tolerant quantum [...]

Figure 1: Evolution of quantum computing on-premise deployments from 2016 to 2024, showing both annual and cumulative numbers of installations. The pie charts illustrate the shift in deployment models between the early period (2016-2022, left) and recent years (2023-2024, right), demonstrating a transition from purchase- and partnership-dominated arrangements to a more balanced distribution, with the research grant model becoming a significant factor. Market Trends and Emerging Patterns The emergence of on-premise quantum computing deployments can be traced through two distinct periods (see Figure 1 above), with the initial phase spanning from 2016 to 2022, which was pioneered by industry leaders.  D-Wave [...]

A Quantum Guide for the Fortune 500 Overview What does it take to persuade the biggest companies in the world to start exploring quantum technology? Twenty years in deep tech consulting is a great place to start. Jean-François Bobier is a partner and director at the Boston Consulting Group in Paris. He uses his expertise in identifying use cases, endless curiosity and computer science background to help Fortune 500 executives understand the quantum world. In this episode of “The Quantum Spin by HKA,” host Veronica Combs discusses story telling and technology with Jean-François. 00:00 Introduction to Quantum Spin Podcast00:36 Interview with [...]

Credit: Quantinuum Perhaps its best to start off explaining what a GHZ state is and why it is an accomplishment to create one that uses 50 qubits. Most people are familiar with two entangled qubits known as a Bell pair such that the state of these qubits are linked such that when one changes a state the other one will also change it state even if these entangled qubits may be far away from each other without any connection. Einstein used to call this "Spooky action at a distance". A GHZ state is an extension of this such that you have [...]

Global Quantum Intelligence (GQI) has just published a report titled The Road to Shor Era Quantum Computing in partnership with the NATO Innovation Fund (NIF). This report provides a comprehensive analysis of the current state of quantum computing and identifies the key factors that will determine the emergence of a dominant design able to break RSA 2048 encryption standards. An Executive Summary of the report is provided in the text below. But to get the complete picture, one should review the full 183 page detailed report. This report provides that best picture anywhere of where the technology is today and describes [...]

Building a Quantum Workforce: Curiosity Required Overview In this episode of 'The Quantum Spin by HKA', Veronica Combs discusses upskilling and reskilling with Professor Dr. Helena Liebelt from the Deggendorf Institute of Technology (DIT). Dr. Liebelt shares her extensive experience in both academia and industry, highlighting the importance of upskilling and preparing a workforce capable of advancing in the quantum and HPC sectors. At DIT, Dr. Liebelt founded the first master’s degree in HPC and quantum computing, designing a program with workforce needs in mind where students spend half the week in classes and the other half working with quantum industry [...]
